Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide an intelligent wellhead heating switch pressure regulating system, which solves the problem that the existing gas well production completely uses manual switch wellhead valves. Due to the large area of ​​the gas field, the remoteness and dispersal of the gas wells, and the influence of the environment, weather, Affected by factors such as roads, manual opening and closing of wellhead valves has seriously affected production efficiency, and the problem that wellhead valves are easy to freeze and block

Abstract

The invention discloses an intelligent well opening heating switch pressure adjusting system. The system comprises a power supply system, a control room operation control platform and a needle valve;the power supply system is electrically connected with the control room operation control platform, the needle valve and a 4G communication and remote terminal unit respectively; the control room operation control platform communicates with the needle valve via the 4G communicate and remote terminal unit; a needle valve controller, an electromagnetic heating controller and an electromagnetic heater are fixedly installed on the needle valve; the needle valve controller is electrically connected with a casing pressure transducer, an oil pressure transducer, a flow transducer and a pipe pressuretransducer respectively; and the electromagnetic heating controller is electrically with a temperature transducer and the electromagnetic heater respectively. The system is scientific and reasonable in structure, convenient and reliable to use and suitable for promotion and use.

Description

technical field [0001] The invention relates to a gas well head device, in particular to an intelligent well head heating switch pressure regulating system. Background technique [0002] With the increase of the production life of gas wells, there are more and more intermittent wells. The intermittent production of intermittent wells is an inevitable stage in the middle and late stages of the life of gas wells. Intermittent production means: with the production of gas wells, the downhole pressure gradually decreases After the reduction to a certain level, the well needs to be shut down, wait for the downhole pressure to increase to a certain value, and then open the well again. This cycle of production is called intermittent opening. The intervals range from one day to one week. The stage of intermittent production lasted for up to 8 years, and the cumulative production accounted for 20%. Taking a certain oil field as an example, intermittent wells account for 25.8% of the...
